Kind of stupid. Run of the mill story. I really don't know what the hype is all about.
This is the comic TPB that inspired the movie Cowboys and Aliens. The two are not even close in the plot. The comic has a pretty strong anti-imperialist message. It compares an alien invasion and takeover of a planet to the European takeover of the America's. I thought it was well done and made you think. Kind of a "see events from another perspective" thing.
